We, the undersigned, request Congress to adopt tax policies that foster economic opportunity and job creation by promoting a resilient, reliable, and cost-effective electric system. We ask you to support the bipartisan Energy Storage Tax Incentive and Deployment Act (S. 1868), a measure that would clarify the investment tax credit (“ITC”) in Section 48 of the tax code includes advanced energy storage as an eligible technology.

While the IRS has previously provided Private Letter Rulings and other administrative guidance on the eligibility of energy storage equipment for Section 48 tax credits, businesses face continuing uncertainty about its application without clear statutory guidance. Additionally, energy storage equipment provides the same services whether or not it is integrated with ITC-eligible resources, although ITC eligibility for stand-alone systems is not clear. If enacted, this bill would increase business certainty, expand access to new private investment, and ensure U.S. energy storage companies scale, create jobs, and become more competitive internationally in the global storage market.
